A New Network RTK—Augmentation Reference Station
-
摘要: 通过分析虚拟参考站技术和主辅站技术的不足,提出了一种新的网络RTK技术———增强参考站技术(ARS)。分析了这种技术的原理并阐述了该技术中改正数的生成方法,同时,提出了一种基于RTCM编码的适合于该技术的改正数编码格式。在此基础上,分析了该技术的RTK定位精度、数据传输效率和系统可靠性,从理论上说明了增强参考站的技术优势。最后,以四川综合GPS服务网(SIGN)的子网数据对该技术进行了验证,结果表明,该技术具有高定位精度、高数据传输效率的特点,是一种理想的网络RTK技术。

Abstract: A new network RTK technology,called augmentation reference station(ARS),which characterizes multiple-baseline difference-positioning technology with the real-time observations of the multiple stations,is proposed under analyzing the shortcomings of VRS and MAC.The principle of ARS is analyzed,its correction generation algorithm is explained,and also a new coding format is developed for correction generation based on RTCM which is suitable for ARS.Then,the accuracy and reliability as well as data transfer efficiency is evaluated in order to present its advantages.Finally,an experiment is carried out to validate the proposed technology with the data of Sichuan integrated GPS Network.The result shows that ARS is a very promising technology with the characteristics in terms of the high positioning accuracy and high data transfer efficiency.-
